Abstract: 1504142 Door closure mechanism EATON Ltd 16 April 1975 [23 May 1974] 23083/74 Heading E2M  In a door closure mechanism, an elongate housing 10 is provided by a cylindrical bore filled with liquid, a first piston head 25 is slidable in the bore and a pinion 27 is in mesh with a rack 26 extending from the first piston head 25 such that the pinion 27 is rotated by means of longitudinal movement of the rack to cause movement of an actuating arm (not shown) connected to the pinion and the door. The first piston head 25 is provided with a unidirectional valve to permit liquid to flow through the piston head only in one direction. A flexible tube 43 extends from one end of the housing through a hole in the first piston head 25 and a flexible sealing washer 45 is associated with the first piston head 25 to make a fluid-tight seal with the bore and with the flexible tube 43 passing through a hole in the washer. When the first piston head 25 is moving towards one end of the housing the flow of liquid can take place only via a valve controlled inlet to the tube adjacent one end of the housing. A second flexible tube 39 extends from one end of the housing through a second hole in the first piston head and a second hole in the washer 45, the second tube 39 being closed at its remote end by a plug 42 but having an aperture 40 in the wall of the second tube. The first piston head 25 is connected by the rack 26 to a second piston head 21 and a third flexible tube 15 extends from the other end of the housing through holes in the second piston head 21 and associated washer 22. A unidirectional valve 24 is provided in the second piston. The flow rate through the ports is controlled by valves 37, 38 and 14.

Abstract: 746,253. Spring balance for sashes. VRIES, A. DE, and VRIES, L. DE. Aug. 12, 1954, No. 23483/54. Class 20(3). A spiral mechanism for a spring balance 20 of the type in which the torque and tension, or compression, forces of a spring are combined to give a constant balancing force; e.g. for a window sash 17 throughout its range of vertical movement, comprises a wire 24 which is spirally wound, with progressively decreasing pitch from top to bottom, around a straight rod 22 and which is provided at its upper end with a twist 46 to slidably engage the rod 22, the latter slidably engaging, by means of a lip 49 on its lower end, the spiral 24. The lower end of an extensible coil spring 26, surrounding the rod 22 and the spiral 24, is non- rotatably secured, together with the lower end of the spiral 24, to a support 27 connected by a bracket 40 to the respective style 19 of the sash. The upper ends of the spring 26 and the rod 22 are secured to a support 29, the end of the rod 22 extending through, and being rotatably mounted by means of a thrust bearing 32 within, a support 31 screwed to the jamb 10 of the window frame, The sash balance has a covering tube 42 and is adapted to fit in a groove 21 in the sash style 19. In operation the varying longitudinal force exerted by the spring 26, as it extends or contracts as the sash is moved, is compensated by the longitudinal movement of torque which is exerted by the spring 26 on the spiral member through the rod 22. In a less complicated embodiment the upper and lower ends of the rod 22 are tightly twisted to securely engage respectively within the upper and lower ends of the spring 26, the upper end of the rod 22 being provided with an eye for screwing to the jamb of the window frame and the lower end having a head. portion rotatively mounted on a bracket secured to the sash. When a compression spring is utilized the convolutions of the spiral member are at a minimum pitch at the upper end. Alternatively, when the convolutions of the spiral member 24 are wound in opposite directions respectively at its upper and lower ends, the pitch being a maximum at the centre, a compression, or tension spring may be employed.
